To all whom it may concern:

Be it known that I, GOTT-DOB KLUMPP', a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented a new and useful Carpet-Cleaner, of which the following is a specification. 1

This invention relates to carpet sweepers and cleaners, and especially to that .class where air forcing apparatus is used to aid objects of my invention are,

of shoe is used to insure the dust and debris being drawn into the cleaner; and, second, to provide a screen of special construction to insure the highest efliciency at all times.

1 In devices of this kind there are two very important-features on which the efiiciency of the cleaner depends. The first is to get the dust from thefioor into the cleaner and at the same time provide means for drawingcoarser objects, as pieces of paper, and the like into the dust box; and the other important feature is to have the strainer through which the air passes kept as clean as possible from the collection of dust-as otherwise this strainer will become clogged and the efliciency of the cleaner will be impaired.

It is the object of my invention to provide acleaner in which both of these important elements will be of the highest efficiency.

My invention is illustrated in the accompanying drawing, in which 35 Figure 1, is a vertical section of a part of a carpet cleaner with my improvements ap-- plied thereto; Fig. 2, is a plan view of the greater portion 0 the shoe which I employ, and of a portion of cleaner bottom; "Fig. 3, is an elevation of the end of the brush showing its relation with the other parts of the cleaner; and Fig. 4, is a plan view of a section of the strainer. I

. In the drawing, like-numerals of reference refer to the same parts in "each of the yiews.

My improvements are shown in connection with a cleaner comprising a rotatable brush 5, adapted to sweep dirt into a body which may be swung on its hinges to permit of the discharge of dust bellows 8, mounted above the dust box operable by a link 9, connected with the wheels 10, whereby the belthe dust box to the bellows'through the openings 11, and discharge the same through or dust box 6, having a hinged bottom 7,

the openings 12, in a manner well understood, the cleaner being movable by a handle special shoe 14, made in one piece, and havlng a central slot 15, through which the brush 5, is free to make contact with the floor, said shoe having depressed segmental walls on each side of said slot, curved to conform in contour with the brush 5, and lie adjacent thereto in action so that the brush will sweep dirt up either the curved wall, 16, or the wall 17, into the dust receptacle according to the direction in which the sweeper, or cleaner is being moved; and, the shoe is provided-with ribs 18, and19, preferably as a continuation of the walls 16, and 17, and adapted to prevent the dirt being thrown out of the dust box after being collected therein. The shoe 14, is suspended through an opening 20, in the bottom 7, of the cleaner by a continuous flexible strip 21, which is preferably in one piece, as shown, with the center 22, cut out for the shoe, and the edges tacked to the bottom 7, and cleats 23 within the dust-box 6, adapted to make close connection between the bottom 7, and the sides of the dust box; and this strip 21, is secured to the shoe in a'manncr to prevent air being drawn between the shoe and strip,-and is secured to the bottom of the cleaner in the same manner, so that all air drawn into the cleaner by the bellows must come through the opening 15, in the shoe, and the opening 22, in the cloth. Adjusted in this way the shoe will rest upon the floor, and slide along the same in close contact therewith whereby air being drawn into the cleaner by the bellows must come from the floor, or carpet, and when drawn through the carpet, will draw the dust from the carpet with it, as will be understood. As the shoe is supported wholly by the strip 21, it is evident that the curved parts thereof will always be in contact with the floor even if the shoe is very light in weight thereby making it unnecessary to employ springs, or weights to increase the closeness of contact; but I do not limit myself to the weight of the shoe alone in so curing close contact with the floor. The advantages of the shoe as shown are that being in one piece there is no chance for leakage of air when the bellows are in operation; and the ease with which the entire shoe can be held in operative position by a single piece of flexible material.

When the cleaner travels over bits of paper, or light material it is often diflicult to'preve'nt the curved sides 16, or 17, driving the paper before the shoe. In order to overcome this difficulty I have provided a plurality of'grooves 24, which preferably alternate'in the bottoms of the curved parts 16, and 17 In operation the air being drawn through these grooves by the action of the bellows will have-the tendency to hold the bits of paper, orother light material to the shoe thereby enabling the shoe to ride over the same until they reach the opening 15, when they will be drawn into the dust box by suction.

While it is important to have a flexiblyinounted shoe that is mounted in an air tight manner and always in contact with the floor; it. is also important to have a strainer cloth always substantially free from dust so that there will be no impediment to the bellows drawing the air through the shoe into the dust box. In order to insure the strainer cloth being as free from dust as possible during the operation of the cleaner I have provided astrainer cloth 25, fastened to the sides of the dust box, and sufiicient in size to hang suspended at the center, preferably in contact with the brush 5, as shown in Fig. 1; and in order that this cloth may always be in contact with the brush, I have provided small weights, or shot 26, preferably mounted in pockets 27, .distributed over the cloth, as particularly shown in Fig.4. By this arrange-- ment, the rotation of the brush, us well as the jarring ofthe machine, will cause the cloth 25, to shake, or be agitated whereby any dust having a tendency to lodge on same will be detached and fall back into the dust box since 1t can not pass out through the opening 15,-in the shoe owing to the constant 'inrush of air caused by the bellows, and can not pass through the strainer cloth. In this way this cloth is always kept. clean; and will coact with the shoe to enable the bellows to work perfectly in the cleaner. y 4

In operation, the cleaner maybe run in either direction; and as it is put in motion I the bellows 8, are also ut in'motion caus ing air to flow inward t rough the opening 15,'m the shoe and out at the top of -the bellows, whlle the strainer. cloth will pre vent dust be drawn through. At thesame time the rush 5, will be rotated to drive into the cleaner, or dust box thereof, the nap of the carpet, or rug, or the threads set forth.

tom opening,

that would not be drawn in by suction alone. As described, all the parts will work together to make a very desirable cleaner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In a carpet cleaner, a body having a bottom with an opening therein, a shoe mounted in said opening having a longitudinal slot therethroughand provided with curved sides adjacent thereto, and a flexible strip of material secured to said shoe and the bottom ofsaid cleaner in an air-tight manner and adapted to centralize and flexibly hold said shoe in said opening in a manner to permit the bottom edges of said curved sides to rest on the floor.

2. In a carpetcleaner, a body having a bottom with an opening therein, a shoe mounted in said opening having alongitudinal slot therethrough and provided with curved sides adjacent to said slot, and a flexible strip of material secured to said shoe and the bottom of said cleaner in an air-tight manner and adapted to centralize and flexibly hold said shoe in said opening in a manner to permit the bottom edges of said curved sides to rest on the floor, said bottom edges having longitudinally-spaced transverse grooves, as and for the purpose I 3. In a carpet cleaner having air-forcing apparatus," a body portion having a bottom opening, a shoe adapted to ride upon the floor and having a central, longitudinal slot therein whereby a nozzle is formed, a flexible strip adapted to position said shoe in said opening and prevent the entrance of air around the same, and a rotatable brush in contact with the floor through said slot, as and for the purpose set forth.
